question 4 (1 point) ✓ saved
microbial cell cytoplasm is composed mostly of
water and protein.
macronutrients in elemental form.
salts and glucose.
peptidoglycan.
question 5 (1 point) ✓ saved
most cultured bacteria tend to multiply by
binary fission.
budding.
fragmentation.
sexual reproduction.

Explanation:

For Question 4: Microbial cell cytoplasm is a complex mixture. Water is a major component as it provides the medium for various cellular processes. Proteins are crucial for functions like catalysis (enzymes are proteins), structural support, etc. Macronutrients in elemental form are part of the cell but not the main components of cytoplasm. Salts and glucose are present but in smaller amounts compared to water and protein. Peptidoglycan is mainly in the cell wall (in bacteria).
For Question 5: Binary fission is the most common mode of reproduction in bacteria. In binary fission, a single - celled bacterium divides into two daughter cells. Budding is more common in some yeast (a fungus). Fragmentation is not a typical mode of reproduction for most bacteria. Bacteria do not usually reproduce by sexual reproduction (though they have mechanisms like conjugation for genetic transfer which is not true sexual reproduction).

Answer:

Question 4: water and protein.
Question 5: binary fission.
